The rack is the linear toothed mechanical component that, inside Bizerba automatic scales, engages with a pinion gear to convert rotary motion into linear movement. This gear is part of the scale's internal movement mechanism, ensuring correct advancement and positioning of the moving parts during everyday operation.

The rack should be replaced when the teeth are worn or stripped, when there is abnormal mechanical play in the sliding motion, or when the connected movement malfunctions (jamming, irregular movement, unusual noise). Replacement part compatible with Bizerba automatic scales, ready for installation.
